<p>stanford does not recalculate GPA. when i asked an admissions officer about the gpa cateogories, she said to not worry about it. just that most people who apply to stanford and get in have very good (meaning straight a's to a couple of b's here and there) academic records. their percentiles thing is "skewed" she said because every school reports grades differently and they don't take the time to recalculate the gpa. they just look at it in context of the school you went to</p>
<p>i think there are different definitions of weighted
i mean, i go to a public school, and I have a 4.0 UNWEIGHTED gpa
so it might be different between public and private schools
just a guess</p>
<p>i wouldnt think stanford lists weighted gpas as most schools weight differently. i know that some schools, including my own, expand upon the a=4, b=3, etc scale by giving an a+ a weight of 4.3, an a a weight of 4, and an a- a weight of 3.7 and so on. im thinking that is likely what is going on, but then again i think it equally likely that stanford recalculates gpa using their own system and is posting those numbers here.</p>
